J. F. DE NAVARRO, OF NEW YORK. N. Y., ASSIGNOR TO EMERY ROTARY `MACHINECOMPANY, OF vSAME PLACE.

Letters Patent No. 92,287, dated July 6, 17869.

The Schedule referred to in these Letters Patent and makixig part ofthesame To all whom fit may concern Be it known that I, J. EDE NAVARRO, ofthecity, county, and State of New York, have invented a new and usefulImprovement in Measuring-Faucets, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawing, forming part ofthis specification, andin which- 'Figure 1represents-a plan of a uxeasnringdaucet,

constructed in accordance with my improvement;

Figure 2, a longitudinal vertical section of the same; and

Figure 3, an inverted plan of the gear by which motion is communicatedto the indicator. l

Similar lletters of reference indicate corresponding parts in theseveral figures.

This limprovement relates to faucets having an indicator-attaehment formeasuring, in fixed or variable quantities, the liquor as it is drawnfrom the cask or vessel; and

The invention consists in a novel and simple combination of' mechanismwith the revolving draught and expelling-devices ofthe faucet, or meansby which the same are operated, for measuring oif the liquor andindicating the quantity drawn.

Referring to the accompanying drawing- A represents themeasuring-cylinder or chamber of the faucet, fitted with suitablerevolving devices for drawing off the liquor through the spigot B, anddischarging it through the nozzle C.

Said draughtdevices are rotated by means of a crank, D, on a main'shaft,E, which passes through a stuiing-box or gland,`F, on the one side .orface ofthe measuring-chamber.

Fitted to rotate freely around this stuiing-box or gland, as a bearingor centre,-is an endless screw, G, formed of a disk, having ascrewthread ont around its edge.

This endless screw is connected with the crank I), through a pin or arm,H, by which means said screw G is rotated with the shaft E, thoughindependent of the latter, by its arrangement around the stufng-box orprojection from the face of the measuring-chamber, which enables me touse a large diameter of screw, without exposing it to objectionableprotrusion, as the same is made to lie close up against the face of themeasuring-cylinder or chamber.

This screw G is made to gear with a'crown-wlieel, I, having its teetharranged worm-fashion, and turning on an arbor, J, screwed into the'topot' the meas. ming-chamber.

Said crown or worm-wheel carries a dial, K, graduated to indicate anydesired quantities-and which operates in connection with an index, M,that is preferably so tinted on to the arbor J, as-that it may be set orturned from one fixed positionto another over therevolving dial, for thepurpose of facilitating the meastiring oiil ofthe liquor, by reversingor setting the index to any desired starting-point or graduation ofquantity on the dial; but, whenset, said indexremains stationary, andthe dial only is made to revolve by the operation of the faucet, tillthe gradnationjon said dial, indicating the quantity to be measured,comes in line with or under the index.

The arrangement ofthe endless screw G in proximity to the face of themeasuring-cylinder A, and so that it rotates with the main shaft Earound an axis common to both, and is in direct gear, as it were,through the worm-wheel I, wit-h the dial, dispenses with muchobjectionable mechanism, and forms a -most simple and eicientcombination for the purpose required'. y Y

-What isrhere claimed, and desired to be secured by Letters Patent, is lt The arrangement, in relation toa measuring-faucet, and its revolvingoperating-shatt E, of the screw'G, the worm-wheel I, and revolving dialK, with ,itsv index M, substantially as shown and described.
